Electricians and Electrical Supervisors
Qualified Person per NFPA
70 E (Definitions)
“One who has skills and knowledge related to the construction and operation of the
electrical equipment and installations and has received safety training on the
hazards involved”
Kent State University Electricians are considered “qualified” to work on electrical
systems and equipment. As a requirement for employment, Kent State University
Electricians are required to successfully pass a written and “hands-on” electrical test
as well as provide proof of extensive electrical work experience. In addition to their
previous safety training, each electrician is required to take regularly scheduled
electrical safety courses provided by the university. Specialized training is also
provided to the electricians for electrical work that requires additional skills such as
medium voltage switching.
Where the Kent State University Arc Flash Study has been completed the label is used
to determine boundary distances, shock hazard, and incident energy. From this
appropriate PPE can be selected. Where the study has not been completed at the date
of this publication, thus, NFPA 70E tables and other sections have been used as the
standard for the safe work practices and levels of required PPE required by the
electricians (including the Electrical Supervisor) (See Part IV).
All university electricians are provided FR rated 8 cal/cm2, long sleeve shirt and pants
as their daily uniform.

Appendix H
Group # 7 – Other University Qualified Employees
A qualified employee is “One who has skills and knowledge related to the construction and operation of
the electrical equipment and installations and has received safety training on the hazards involved”.
This group of employees, described in Appendix A, is normally restricted to working on equipment in a
de-energized state. Therefore, their exposure to electrical hazards will only occur while de-energizing
and verifying a zero energy state. During this process, the employee must use proper lockout/tagout
procedures. This employee must use the information provided on the label where an arc flash survey has
been completed or determine the HRC found in Appendix K to select the appropriate PPE, Appendix L,
that must be worn where an Arc Flash label is not present.
On rare occasions, it might be necessary to troubleshoot laboratory equipment while the equipment is
energized. This should only be done as a last resort, and only done when the employee is “qualified”
through experience and training to recognize the electrical hazards while working on any piece of
equipment. When doing so, the employee must read and understand the labels where an arc flash survey
has been completed or determine the hazard risk category do that appropriate PPE can be selected.
In no case, shall this group of employees install or repair electrical equipment other than what is described
above. This group of employees is limited to no more than 240 volts and HRC 2/ 8 cal/cm2, and only
after that they received specific training and experience to conduct this category of electrical work safely.

Rubber insulating gloves are gloves rated for the maximum line-to-line voltage upon which work will be done.
Insulated and insulating hand tools are tools rated and tested for the maximum line-to-line voltage upon which work will be done, and
are manufactured and tested in accordance with ASTM F 1505, Standard Specifications for Insulated and Insulating Hand Tools.
The use of “N” does not indicate that rubber insulating gloves and insulated and insulating hand tools are not required in all cases.
Rubber insulating gloves and insulated and insulating hand tools may be required by 130.4, 130.8 (C) (7), and 130.8 (D).
For equipment protected by upstream current limiting fuses with arcing fault current in their current limiting range (1/2 cycle fault
clearing time or less), the Hazard/Risk Category required may be reduced by one number.
For power systems up to 600 V the arc flash boundary was determined by using the following information: When 0.03 second trip
time was used, that indicated MCC or panelboard equipment protected by a molded-case circuit breaker. Working distance used was
18 in. (455 mm). arc gap used was 32 mm for switchgear and 25 mm for MCC and protective device type 0 for all. When 0.33 or 0.5
second trip time was used, that indicated a LVPCB (drawout circuit breaker) in switchgear. Working distance was 24 in. (610 mm).
Arc gap used was 32 mm and protective device type 0 for all. All numbers were rounded up or down depending on closest multiple of
5.
For power systems from 1kV to 38 kV the arc flash boundary was determined by using the following information: No maximum
values were given in the 2009 edition of NFPA 70E for short-circuit current or operating time. Two sets of equations were performed:
35kA AIC and 0.2 second operating time and 26 kA AIC and 0.2 second operating time. 0.2 seconds was used by adding the typical
maximum total clearing time of the circuit breaker to an estimated value for relay operation. This coincides with the IEEE 1584
values of 0.18 second operating time and 0.08 tripping time rounded off. A short-circuit current of 35 kA was used as a maximum
(HRC-4 @ ~ 40 cal/cm2). Working distance used was 36 in. (909 mm), arc gap was 6 in. (455 mm), and protective device type 0 for
all.

If rubber insulating gloves with leather protectors are required by Table 130.7(C)(9), additional leather or arc-rated gloves are not
required. The combination of rubber insulating gloves with leather protectors satisfies the arc flash protection requirement.
Face shields are to have wrap-around guarding to protect not only the face but also the forehead, ears, and neck, or, alternatively, an
arc-rated arc flash suit hood is required to be worn.
Arc rating is defined in Article 100 and can be either the arc thermal performance value (ATPV) or energy of break open threshold
(Ebt), ATPV is defined in ASTM F 1959, Standard Test Method for Determining the Arc Thermal Performance Value of Materials for
Clothing, as the incident energy on a material, or a multilayer system of materials, that results in a 50 percent probability that
sufficient heat transfer through the tested specimen is predicted to cause the onset of a second-degree skin burn injury based on the
Stoll curve, in cal/cm2. Ebt is defined in ASTM F 1959 as the incident energy on a material or material system that results in a 50
percent probability of breakopen. Arc rating is reported as either ATPV or EBT, whichever is the lower value.
